Application filed May 22,

T 0 all whom it may concern:

Be it known that I, Aoons'r PRYM, a subject of Germany, and residing at Busbach, near Stolberg, Rhine State, Germany, have invented a certain new and useful Press Button, of which the following is a specification.

This invention relates to improvements in press buttons and more particularly to press buttons of the type which are secured to the supporting material by means which eliminates the necessity of piercing the material or sewing the two halves of the press button in position. I

The primary object of the invention is to furnish a press button with improved detachable means for securing the two halves of the press button to the supporting material.

Another object of the invention is to furnish a detachable means for securing press button halves in position and provided with permit said means Fig. 2 1s a similar view of the ball or head member of the press button Fig. 3 is a plan view of a securing spring or resilient member.

Fig. 4 is an elevation of the latter.

The press button halves a are provided with annular skirts 6 extending in the direction of the supporting material 0Z. Each of these annular skirts is provided with an inwardly extending flange e adapted to contact with a securing sprlng or resilient ring 0 for holding each of the press button halves in engagement with the supporting material d. It will be noted that the spring in expanding will force a portion of the supporting material beneath the flange 6 so that each press button half will be securely held same to be removed.

in engagement with the supporting material. p I

As shown in Figures 3 and a, the spring member 0 is provided with a loop or finger engaging member g, which, in the socket piece, bears on the dome or cap it and presses the supporting material thereon. By grasping the part 9 the spring 0 may be readily removed from thepressbutton halves.

From the foregoing it isbelieved that the s construction, operation and advantages of the invention may be readily understood by those skilled in the art, and it is apparent that changes may be made in the construe tion disclosed, without departing from the spirit of the invention as'expressed in the claims. I

What I claim and desire to secure by Letters Patent is,-

1. In a press button adapted to be secured in position without piercing its supporting material, an edge and a flange bent towards the material, and a freely detachable resilient split ring member holding the material under the said flange, said ring member being contractable in order to permit the 2, Ina press button which is secured in position without piercing its supporting material, an edge and a flange which are, bent towards the material, an annular spring member holding the material under the said flange and a loop on the spring member, lying in a plane outside the plane of the said flange.

3 In apress button which is secured in positlon without piercing its supporting material', an edge and agfiange, which are bent towards the material, a cap on the socket-piece and a loop on the spring mern the plane of her lying in a plane outside the material the said flange and pressing against the said cap.

r 4. In a press button which is secured in position without piercing its supporting material, an edge and a flange which are bent towards the material, aresilient ring member holding the material under the said flange, and a fin er engaging member extending from sai ring to permit the ring to be readily detached. I

5. A press button as claimed in claim 1 in which said resilient ring member and finvgel engaging member consists of a single piece of Wire having the portion intermediate its ends shaped to form a loop, the
